Question

In ΔWXY, the measure of ∠Y=90°, WX = 7.9 feet, and XY = 6.7 feet. Find the measure of ∠X to the nearest tenth of a degree.

Answer 1

Answer:

X=31.9943≈32  

Step-by-step explanation:

cosX=  

hypotenuse

adjacent=  

7.9

6.7

cos X = \frac{6.7}{7.9}

cosX=  

7.9

6.7

​  

 

X=\cos^{-1}(\frac{6.7}{7.9})

X=cos  

−1

(  

7.9

6.7

​  

)

X=31.9943\approx 32^{\circ}

X=31.9943≈32
